At its Düsseldorf site, the Bundesbank operates a Public Key Infrastructure (PKI). This PKI uses a two-stage certification structure with self-signed root certificates. The root CA certificates certify only downstream specialist CAs.
The Bundesbank is a member of the TeleTrusT European Bridge CA (EBCA). The certificates issued by the Bundesbank's PKI meet the advanced signature requirements stipulated in the German electronic signature law (Gesetz über Rahmenbedingungen für elektronische Signaturen).
